The v1.0 display can't do brightness, except in binary form (backlight on or off). In my living room I have one Pi that has an Adafruit TSL2561 Light Sensor (pointing out the side of a translucent case), and a Python script that takes a lux reading every 15 seconds and posts that reading to an in-ho...

CarlRJ

Given the bit about it being on a boat, with unreliable power, I would strongly suggest setting it up as a system that is run from either an actual UPS, or a scratch-built UPS equivalent, with the Pi drawing from large batteries, which are recharged as necessary from solar/alternator/whatever. Pi's ...

Surely many Raspberrians must have dealt with interfacing a Pi to an (electrically) noisy, >5V environment? In cars, for example? Plenty of people have done Pi-in-car projects, some of them have posted here looking for help or detailing their results. I've never seen any of them mention the HAT you...

Would something like this: Waterproof DS18B20 Digital temperature sensor , or this: Platinum RTD Sensor - PT100 , or this: Thermocouple Type-K Glass Braid , work? They all tend to be on one meter cables, but at least some of them would be amenable to splicing on additional cable, or you could hook o...

Others have asked this before, the answer has generally been: you won't get it deleted, just change the password to something you're unlikely to remember and walk away from the account (though possibly the recent upgrade of the forum software has added some way). You've only written this one post, t...

...Pi3A that have no such restrictions.
Is that an incipient launch announcement? (Hope springs eternal...)

I... wondered about that too.

Thanks for mentioning the make and model of the battery that worked for you. SIKE!

You start out by throwing shade at a fellow forum member, and then ask everybody to take time to give you assistance and advice. How's that working out for you?

I said aside from the Pi links etc. What is the VC5s benefit over competing tech. What can it do better? What can it do better than competing tech? Offer more speed/capability than the VC4 while providing backward compatibility with the Pi . Other CPU/GPU combinations, or SoC's, like an ARM/Mali pa...

Actually, from what I hear, it wasn't the forum software that broke.....that software worked exactly as it was supposed to do. As for the programming, that is down to the PHPBB developers, not us. Our team are putting together a new skin (with some minor SW changes IIUIC), not the underlying functi...

The message that appears telling you you have been banned is important. Just saying "Not now Josephine" or similar doesn't get across the point. The message is important, if it is truthful . If someone in the office temporarily put in a wildcard ban of 0.0.0.0/0 or some other enormously broad wildc...

CarlRJ

As I metioned, until this "banning bug" is fixed, you should always do ^A^C (select ALL, Copy to Clipboard) just before clicking Submit. Yep, though in my case it's Cmd-A, Cmd-C. I usually only do that on untrustworthy forums (i.e. ones where I've had problems losing text) - this forum has never fa...

CarlRJ

Yes, because it does. Rest assured that we are aware of such issues as dynamic IP addresses. These reports are not about a real ban though. It's probably some bug in accessing the database. It would be much better if the failure mode for "failed trying to access the db to see if IP is banned" was "...

It appears the RPI theme is using full justification (vs. flush left aka "ragged right") - please don't do that. It makes pages pretty at the expense of making them harder to read. Please let readability win.

CarlRJ

We've just added the standard website top bar to the RPI theme - what do people think? ARRRRGH!!!! I just wrote a lengthy reply to this, clicked Submit , and my reply seems to have been thrown away by the forum! That is SO FRUSTRATING! The non-scrolling top bar is a bad thing - just as in about 90%...

CarlRJ

On the default theme (raspberry_pi): 1. As suggested, dim the signatures/last-edited section (maybe gray instead of black text?) and make it a bit smaller (maybe 70%-80%?), to put more focus on people's words rather than boilerplate. 2. I'd really like to see something done to set the Stickies off a...

I inform you that, here, in 2017, exist all kind of monitor bigger than 640*480!!! ...
Considering the ever-increasing use of phones and tablets, you have not done a good job.

Reports of problems are helpful. Snide remarks are not called for.

Limited availability has really gotten in the way of my plan to tile my living room walls with Pi Zeros.

Im wondering if anyone was able to have a script running 24/7 on a rbp that will check periodically for any website changes and notify via email if found any. You say, "any website changes" - do you mean any website on the entire internet, or any change to any page on a particular website, or any c...

We need a picture of jamesh riding a rainbow unicorn while holding a Pi 5B ;-) I have one, but I'm planning to make millions by selling it to the National Enquirer. Had this thread as an open tab for a while, intending to suggest it might be better form to be a bit more gracious towards our hard-wo...

CarlRJ

Just to add to the chorus: if a Pi appears to meet your needs (from this thread it sounds like it does), then get a Pi 3B now, don't wait for the next model (it almost certainly won't appear this year, and might not appear next year). If a Pi 4 comes along in a year or two, and you are persuaded tha...

I would like to see USB3 or c support event if it took a second Power supply. Still would like at least two USB3/c ports. If you are redoing the GPU then how about 4k support. The factor preventing USB3 (or C) is that the IO path into the current SoC for that is a single USB2 interface. So, again, ...

CarlRJ

As the Foundation introduced the Pi Zero, would it be out of the question to see a "Pi Advance"? I suppose a stronger GPU and 2GB ram would be at the top of many wish lists. I do wonder what could be possible for about £55... The Pi Advance you describe could possibly sell for £55... after spending...

CarlRJ

Much as I love prominent official announcements, it might better if this one, when it comes, is done quietly. I would envision several thousand people suddenly ordering anywhere from 5 or 6 Pi0/Pi0W boards to 100+ boards all at once and stripping the supply within minutes...a phenomenon we have all...

There is some facility in the SD card spec for password protection, but to my knowledge*, there is no code in any of the Linux versions normally used on the PI to make use of the SD card's password protection capabilities. I've seen others ask about it numerous times, and I believe the answers are a...

So, this Christmas, can we expect to see Pi Zero-W's given away free with half a pint of fresh cream? Yes, though due to an unfortunate misinterpretation of instructions between the two factories on how the promotion was to be run, the Pi Zero-W's have been sealed, unprotected, inside the pints of ...
